Technical Information - Indicators
The majority of Arcolectric indicator lights can be supplied with alternative light sources:
Neon, Incandescent lamp or LED.
NEON and FLUORESCENT LAMPS
Colours
Red, Amber, Clear Neon and Green Fluorescent.
Maximum striking voltages
Standard brightness types 65Vac 90Vdc,
High brightness types 85Vac 135Vdc.
High brightness types are usually fitted.
Life
Typically 25,000 (Green fluorescent lamps 20,000
hours). (Measured to a point when light output is
half that of its original level.)
The end of life for a neon lamp is not usually a
sudden failure.
FILAMENT LAMPS
Colours
Red, Amber, Green, Clear and Blue.
LEDS
Colours
Red, Yellow, and Green.
Voltage
Basic voltage 2.0/2.2V. Some items are available
with integral resistors for 12V use. For details of
resistors required for higher voltages please
contact our Sales department.
Current
Maximum continuous forward current 35mA.

False signals due to long wiring
It is possible for a neon or fluorescent indicator to
glow when it should be off.
These false signals are caused by the capacitance
effect when fairly long wiring leading to the
indicator is adjacent to other live cables.
This effect can be prevented in most cases by
fitting a 100K resistor across the supply wires to
the indicator assembly.
